Mobile Protective Housing for Pathogen Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective devices against pathogens, such as chemical protection suits, are cumbersome and time-consuming to use, making them impractical for infants, seniors, sick, and disabled individuals.
Innovation Solution
A protective device with a compact, airtight housing that allows easy entry and exit, equipped with a seating element and a chassis for mobility, providing protection against pathogens through airtight sealing and easy access, suitable for various environments and user types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional protective devices like chemical protection suits are used, then protection against pathogens is provided, but the device becomes cumbersome and time-consuming to use
Solution Approach 1:
The protective device is segmented into a mobile protective housing that can be separated from the seating element, allowing the housing to be sterilized independently while maintaining protection functionality. This segmentation enables the protective function to be preserved while simplifying the overall system operation.
Solution Approach 2:
A mobile protective housing acts as an intermediary between the user and the pathogen-containing environment. The housing can be sterilized and disposed of after use, while the seating element remains reusable, thus providing protection without requiring the entire system to be cumbersome or time-consuming to prepare.
2Reliability
If traditional protective devices are used, then protection against pathogens is provided, but the device becomes complex in structure and procedure
Solution Approach 1:
The protective device is divided into distinct functional segments: a mobile protective housing that provides the airtight barrier and can be sterilized independently, and a separate seating element that provides user comfort. This segmentation reduces overall structural complexity by allowing each component to be optimized independently.
Solution Approach 2:
The protective housing is designed to be self-contained with integrated sterilization capabilities and mobile components, allowing it to be prepared and maintained without complex external systems. The housing can be independently sterilized and moved to different locations, reducing the need for complex infrastructure.
3Reliability
If traditional protective devices are used, then protection against pathogens is provided, but the device requires significant time to don and doff
Solution Approach 1:
The protective housing is pre-sterilized and prepared in advance, eliminating the need for time-consuming sterilization procedures at the point of use. The mobile design allows the housing to be pre-positioned and ready for immediate use, significantly reducing the time required to don protective equipment.
Solution Approach 2:
The protective housing is designed as a disposable component that can be sterilized and disposed of after a single use or limited number of uses. This eliminates the time-consuming process of donning and doffing complex reusable protective suits, as the housing can be quickly removed and replaced with a pre-sterilized unit.
4Reliability
If the protective housing completely closes the interior space, then protection against pathogens and radiation is improved, but communication with the environment becomes more difficult
Solution Approach 1:
The mobile protective housing serves as an intermediary that maintains a completely closed interior space for protection while incorporating communication interfaces such as microphones, speakers, and cameras that enable two-way communication between the user and the external environment without compromising the airtight seal.

AI summary
A protective device to protect against pathogens comprises a protective housing that defines an interior space defined, a closable access opening to enter the interior space, a seating element that allows a passenger to sit in the interior space, and a chassis to move the protective device, wherein the protective device, in a closed state, seals the interior space in an airtight manner against an environment. A method to protect against pathogens comprises providing a protective device to a passenger, closing the protective device in an airtight manner, and moving the protective device. The protective device and/or the method may be used to protect a patient.
